The chapters in this volume aim to advance the discussion of the role of the a priori in philosophy by addressing four sets of issues. The first is whether intuitions provide evidence for philosophical theories, whether that evidence is a priori, and whether the results of experimental philosophy affect the evidential or a priori status of intuitions. The second is whether there are explanations of the a priori and what range of propositions can be justified and known a priori. The third is whether a priori justified beliefs are needed in order to avoid some skeptical worries. The fourth is whether certain recent challenges to the existence or significance of the a priori are successful.Less

The A Priori in Philosophy

The chapters in this volume aim to advance the discussion of the role of the a priori in philosophy by addressing four sets of issues.

The second is whether there are explanations of the a priori and what range of propositions can be justified and known a priori. The third is whether a priori justified beliefs are needed in order to avoid some skeptical worries.

Abstract objects such as properties, propositions, numbers, degrees, and expression types are at the centre of many philosophical debates. Philosophers and linguists alike generally hold the view that natural language allows rather generously for reference to abstracts objects of the various sorts. The project of this book is to investigate in a fully systematic way whether and how natural language permits reference to abstract objects. For that purpose, the book will introduce a great range of new linguistic generalizations and make systematic use of recent semantic and syntactic theories. It will arrive at an ontology that differs rather radically from the one that philosophers, but also linguists, generally take natural language to involve. Reference to abstract objects is much more marginal than is generally thought. Instead of making reference to abstract objects, natural language, with its more central terms and constructions, makes reference to (concrete) particulars, especially tropes, as well as pluralities of particulars. Reference to abstract objects is generally reserved for syntactically complex and less central terms of the sort the property of being wise or the number eight.Less

This book introduces Immanuel Kant's masterwork, the Critique of Pure Reason, from a ‘relaxed’ problem-oriented perspective which treats Kant as an especially insightful practising philosopher, from whom we still have much to learn, intelligently and creatively responding to significant questions that transcend his work's historical setting. The book's main project is to command a clear view of how Kant understands various perennial problems, how he attempts to resolve them, and to what extent he succeeds. The constructive portions of the First Critique—the Aesthetic and Analytic—are explored in detail; the Paralogisms and Antinomies more briefly. At the same time the book is an introduction to the challenges of reading the text of Kant's work and, to that end, selectively adopts a more rigorous historical and exegetical stance.Less

This book explores a particular way of justifying the rational principles that govern credences (or degrees of belief). The main principles that the book justifies are the central tenets of Bayesian epistemology, though many other related principles are met along the way. These are: Probabilism, the claims that credences should obey the laws of probability; the Principal Principle, which says how credences in hypotheses about the objective chances should relate to credences in other propositions; the Principle of Indifference, which says that, in the absence of evidence, credences should be distributed equally over all possibilities that are entertained; and Conditionalization, the Bayesian account of how responses are planned when new evidence is received. Ultimately, then, the book is a study in the foundations of Bayesianism. To justify these principles, the book looks to decision theory. An agent’s credences are treated as if they were a choice she makes. The book appeals to the principles of decision theory to show that, when epistemic utility is measured in this way, the credences that violate the principles listed above are ruled out as irrational. The account of epistemic utility given is the veritist’s: the sole fundamental source of epistemic utility for credences is their accuracy. Thus, this is an investigation of the version of epistemic utility theory known as accuracy-first epistemology.Less

This book pursues some novel and unusual standpoints in the philosophy of action. It rejects, for example, the most widely held view about how to count actions, and argues for what it calls a ‘prolific theory’ of act individuation. It also describes and argues against the two leading theories of the nature of action, the causal theory and the agent causal theory. The causal theory cannot account for skilled activity, nor for mental action. The agent causalist theory unnecessarily reifies causings. The book identifies an assumption that they share, and that most action theorists have assumed to be unproblematic and uncontroversial, that an action is, or entails the existence of, an event. Several different meanings to that claim are disentangled and in the most interesting sense of that claim, the book denies that it is true. The book's own alternative is simple and unpretentious: nothing informative can be said about the nature of action that explicates action in any other terms. The book sketches a theory of causal explanation of action that eschews the requirement for laws or generalizations, and this effectively quashes one argument for the oft-repeated view that no explanations of action can be causal, on the grounds that there are no convincing cases of laws of human action. It addresses a number of questions about the knowledge an agent has of his own actions, looking particularly at examples of pathological cases of action in which, for one reason or another, the agent does not know what he is doing.Less

Human agency has four irreducibly different dimensions—psychological, ethical, intellectual, and physical—which the traditional idea of a will tended to conflate. Examining them separately yields several significant results. First, the mark of human agency in general, like that of every kind of agent with functionally differentiated parts, is functional integration, not intention. Second, voluntariness is an ethical concept, unlike either intention or agency as such, and it is defined in negative not positive causal terms: an act is voluntary if it is not due to ignorance or compulsion, the connection between these factors being that both are normally exculpations. Third, acting intentionally cannot be defined as acting for a reason because intentional action is a manifestation of desire whereas action done for reasons is a manifestation of knowledge or belief. Furthermore, explanations that simply give agents’ reasons, e.g. ‘He took the left fork because it was the road to Larissa’, differ significantly from ones that refer to belief, e.g. ‘He took the left fork because he believed it was the road to Larissa’. For the first explanation mentions a fact about the traveller’s situation he knew and took into consideration, whereas the second merely mentions his state of mind. Drawing this distinction between these different kinds of explanations leads to a new theory of knowledge as an ability that is exercised in rational thought and behaviour, and thereby a new solution to the puzzle in the Meno about whether knowledge is a better guide to action than true belief.Less

Infinitism is an ancient view in epistemology about the structure of knowledge and epistemic justification. Infinitism has never been popular, and is often associated with skepticism, but after languishing for centuries, it has recently begun a resurgence. This book collects together fourteen chapters of cutting edge research on infinitism. The chapters shed new light on infinitism’s distinctive strengths and weaknesses and address questions, new and old, about infinitism’s account of justification, reasoning, epistemic responsibility, disagreement, and trust, among other important issues. This book clarifies the relationship between infinitism and skepticism, coherentism, foundationalism, and contextualism, and it offers novel perspectives on the metaphysics and epistemology of regresses.Less

According to the popular coherence theory of knowledge and justification, if a person's beliefs are coherent, they are also likely to be true. This book is the most extensive and detailed study of coherence and probability to date. The book takes the reader through much of the history of the subject, from early theorists like A. C. Ewing and C. I. Lewis to contemporary figures like Laurence BonJour and C. A. J. Coady. The arguments presented are general enough to cover coherence between any items of information, including those deriving from belief, memory, or testimony. It is argued that coherence does not play the positive role that it is generally ascribed in the process whereby beliefs are acquired. The opposite of coherence, incoherence, is nonetheless the driving force in the process whereby beliefs are retracted.Less

Is it ever possible for people to act freely and intentionally against their better judgement? Is it ever possible to act in opposition to one's strongest desire? If either of these questions are answered in the negative, the common-sense distinctions between recklessness, weakness of will and compulsion collapse. This would threaten our ordinary notion of self-control and undermine our practice of holding each other responsible for moral failure. So a clear and plausible account of how weakness of will and self-control are possible is of great practical significance. Taking the problem of weakness of will as her starting point, Jeanette Kennett builds an admirably comprehensive and integrated account of moral agency which gives a central place to the capacity for self-control. Her account of the exercise and limits of self-control vindicates the common-sense distinction between weakness of will and compulsion and so underwrites our ordinary allocations of moral responsibility. She addresses with clarity and insight a range of important topics in moral psychology, such as the nature of valuing and desiring, conceptions of virtue, moral conflict, and the varieties of recklessness (here characterised as culpable bad judgement) — and does so in terms which make their relations to each other and to the challenges of real life obvious. Agency and Responsibility concludes by testing the accounts developed of self-control, moral failure, and moral responsibility against the hard cases provided by acts of extreme evil.Less

Constitutivism is the view that we can derive substantive normative conclusions from an account of the nature of action. Agency and the Foundations of Ethics explains the constitutivist strategy and argues that the attractions of this view are considerable: constitutivism promises to resolve longstanding philosophical puzzles about the metaphysics, epistemology, and practical grip of normative claims. Yet constitutivism faces a challenge: it must employ a conception of action that is minimal enough to be independently plausible, but substantial enough to yield robust normative results. The current versions of constitutivism fall short on this score. However, we can generate a successful version by employing a more nuanced theory of action. Drawing on recent empirical work on human motivation as well as a model of agency indebted to the work of Nietzsche, the book argues that every episode of action aims jointly at agential activity and power. An agent manifests agential activity if she approves of her action, and further knowledge of the motives figuring in the etiology of her action would not undermine this approval. An agent aims at power if she aims at encountering and overcoming obstacles or resistances in the course of pursuing other, more determinate ends. These structural features of agency both constitute events as actions and generate standards of assessment for action. Using these results, the book shows that we can extract substantive normative claims from facts about the nature of agency.Less
